Excerpt:
Considerable attention has been given to the effect of heating in various media on the viability and virulence of the spores of Bacillus larvae, the causative agent of the honeybee disease, American foul brood (White, 1920). Few data have been reported, however, concerning temperatures above the boiling point of honey (White, 1920; Burnside, 1940a, 1945). Under a project on sterilization of honey to permit feeding it to bees without danger of spreading disease, thermal death-time studies were conducted on spores of this organism in diluted honey over a temperature range of 100 to 140 C. The results reported here have been used in the development of a process for treatment of honey to permit feeding it to bees without danger of transmission of American foul brood.
